Rise of the Shadow

"After their parents vanished, Alex and Emma are sent to live with strict Uncle Mordo. Only Emma's pet rabbit, Pimawa, keeps them company. But when flying skeletons called Rag-o-Rocs storm their once-quiet home, the kids escape just in time with Pimawa leading the way. The rabbit takes the siblings to the Conjurian, a land where magic exists and Pimawa can talk. But the Conjurian is in trouble. Magic has been disappearing, and the Shadow Conjurer, the most mysterious sorcerer of all, is on the hunt for the Eye of Dedi, an object so powerful it could destroy the Conjurian and human worlds. The battle to control all magic has begun. There's only one problem: Alex and Emma don't have any!"--Amazon.com.
